Hello all,
I have a shapefile with MULTIPOINT shapetypes that I need to convert to
a shapefile with POINT shapetypes. I have create some code that to do
this, but I get a NullPointerException in the Geotools code. Please take
a look at the code below:
I change the original schema file with the following code:
AttributeType[] attributeTypes = schema.getAttributeTypes();
attributeTypes[schema.find("the_geom")] =
AttributeTypeFactory.newAttributeType("the_geom", Point.class);;
FeatureType newSchema =
FeatureTypeBuilder.newFeatureType(attributeTypes, schema
.getTypeName(), schema.getNamespace(), schema.isAbstract(),
schema.getAncestors(),
schema.getDefaultGeometry());
I change the features with the following code:
Geometry geom =
feature.getDefaultGeometry().getInteriorPoint().getGeometryN(0);
feature.setDefaultGeometry(geom);
Then I write all the features to a new shapefile:
ShapefileDataStore outStore = new
ShapefileDataStore(outputSHP.toURI().toURL());
outStore.createSchema(newSchema);
FeatureWriter outFeatureWriter =
outStore.getFeatureWriter(outStore.getTypeNames()[0],
Transaction.AUTO_COMMIT);
for (Feature feature : features) {
// Get the next, empty feature from the writer
Feature writeFeature = outFeatureWriter.next();
att = feature.getAttributes(att);
for (int n = 0; n < att.length; n++) {
writeFeature.setAttribute(n, att[n]);
}
outFeatureWriter.write();
}
// line below is essential, incomplete files are written without it!
outFeatureWriter.close();
When I run the above code I get a NullPointerException at
org.geotools.data.shapefile.ShapefileDataStore$Writer.write(ShapefileDat
aStore.java:1595).
I don't see how I can solve this. Does anyone see what I'm doing wrong
here or how I can do the conversion?
Thanks in advance,
Jeroen
